LAMP-GUARD.

Specification of Letters Patent.

Patented Aug. '7, 1906.

Application filed October 3, 19045 Serial No. 227,043.

To all whom it may concern:

Be it known that I, CHARLES MOLITOR, a

citizen of the United States, residing at Chisuch as will enable others skilled in the art to which it appertains to make and usethe same.

My invention relates toa novel construction in. an incandescent-lamp guard, the object being to provide a durable and eflicient device of this character from which incandescent lamps may be readilyremoved and replaced; and it consists in the features of construction and combinations of parts *hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is a central longitudinal section of a lamp-guard constructed in accordance with my invention. Fig. 2 is a horizontal section of same on the line 2 2 of Fig. 1. Fig. 3 is a fragmentary detail section, on an enlarged scale, on the line 3 3 of Fig. 2. Fig. 4 is a detail fragmentary section, on an enlarged scale, on the lines 4 4 of Fi 1.

lily said device comprises a handle A, having a central longitudinal opening B, which is threaded adjacent its upper end to receive the threaded sleeve 0. At its upper end, concentric with. said central opening, I provide an annular recess D on said handle,'upon which the plate E is adapted to rest, said plate E having a central opening adapted to receive the raised portion F of said handle between said central opening and said annular recess D. The said plate E is provided with a plurality of lugs G, which are adapted to be forced into the wood or other material of which said handle A is made to hold said i latefirmly in position thereon. The said plate E is further held'in place on said handle Aby means of the washer H, of non-conducting material, upon which a metallic nut J bears, said nut being mounted on the proj ecting portion of said threaded sleeve C; the latter being adapted to receivethe lampsocket. A funnel-shaped reflector K may be mounted in my said device, such reflector being provided with a central opening and flat bottom, forming, substantially, an internal annular flange which is adapted to be clamped between said nut J and washer H. On the upper and lower faces of said plateE are mounted a plurality or radially-disposed bars -L and M, respectively, said bars M being ofgreater length than said bars L and both said bars projecting beyond the periphery of said plate; The-said bars are preferably secured inplace by=means of rivets N passed through the same and through said platednwardly of the edge ofthe latter and. considerably inwardly of the free ends of said bars, and the freeends of said bars constituting thereby spring tongues'the purpose of which will be hereinafter "more fully described.

The said handle and bars mounted thereon,

aszhereinbefore described, form, substantially, thesupporting part of the device, the guard proper comprising-a cage N, which is adapted tobe removably mounted on said support and which comprises a base 0, consisting of a ring, preferably having an'annular peripheral flange for reinforcing same and the inside diameter of which coincides closely. with the diameter of said plate E, which it is adapted to receive. The said ring 0 is provided on its inner edge with a plurality'ofrecessesP, conforming in number and relative location with the free ends of the bars L, which are adapted to pass through said recesses, and by then relativelyturning said base 0 and handle A the saidbase or ring 0 will be held between the two sets of bars L and M, and thus firmly supported on said handle A. Adjacent each of said recesses P the said ring 0 is provided with projections Q, over which the free ends of said bars L are sprung when said base and handle A are relatively turned, said projections serving, substantially, as lugs to hold said members in-relative position. To further lock the same, however, I provide in place of one of the outermost rivets passingthroughone set of said bars L and Ma sets'crew R, which passes freely through the bar M and through a threaded opening in said bar L.. By turning said set-screw the said bars L and M are obviously to be drawn firmlytogethe'r, and thus clamp said ring O between their free ends 'andabsolutelyprevent. revolution thereof. The body of said cage, N consists of a plurality of parallel vertical wires, which at their lower endsare secured in said base .or ring 0, preferably by means of upsetting the extreme ends thereof, and thus riveting same in said base in a wellknown manner, and at their upper ends passing through a reinforcing-ring S, in, which alternate bars are likewise secured, the remaining bars being extended upwardly and their ends bent over, as at T, the extreme free ends of said curved portions T being threaded and secured in a hub U, which is provided with threaded radial openings to receive such threaded ends. also secured a hook V, by means of which the guard may be hung where desired. In the manufacture of my said guard the said bars, having the curved ends T, must obviously be first secured in said hub U and the rings 0 and S then inserted over said bars-and secured. I

My said device is extremely simple, ,efiicient, and durable, and the lamps to be contained therein may obviously be very readily and rapidly interchanged;

I claim as my invention- 1. In a lamp-guard, the combination with a supporting member adapted to carry the lamp, of a cage adapted to be removably mounted on said supporting member and receive said lamp, said cage consisting of a hub provided with a central threaded opening adapted to receive the threaded end of a hook and having a plurality of radially-disposed threaded openings communicating with said central opening, a plurality of bars having threaded ends adapted to enter said openings and bear against the threaded end of said hook, said bars being curved at their threaded end portions and the free ends thereof disposed parallel to each other, a base and a reinforcing member each provided with openings to receive said bars and disposed at the extreme free ends and between the ends of said bars respectively and there secured, and intermediate bars alternating with said firstnamed bars and sec ured at their ends in said base and reinforcing member.

2. A lamp-guard comprising in combination, a supporting member consisting of a handle provided with a central opening, a threaded sleeve mounted in said central open- I ing and projectingbeyond' one end of said handle, said handle being provided with an annular recess at said end, a plate having a central opening mounted on said end of said handle and fitting said recess adjacent said 5 central opening, projecting supporting-arms on said plate, projecting yielding clamping devices on said plate, a washer of non-conducting material on said sleeve, a nut disposed on said sleeve and bearing on said washer, and a guard member consisting of a cage having a base provided with a central opening to receive said plate on said handle, and having internal recesses for the passage of said pro ecting clamplng members, said In said hub is guard member and said supporting member being adapted to be relatively revolved to throw said clamping members out of alinement with said recesses to secure said cage.

3. A lamp-guard comprising in combination, a supporting member consisting of. a handle provided with a central opening, a threaded sleeve mounted in said central opening and projecting beyond one end of said handle, said handle being provided with an annular recess at said end, a plate having a central opening mounted on said end of said handle and fitting said recess adjacent said central opening, projecting supporting-arms on said plate, projecting yielding clamping devices on said. plate, a washer of nonconducting material on said sleeve, a nut disposed on said sleeve and bearing on said washer, and a reflector disposed on said sleeve and engaged by said nut to hold same in place, and a guard member consisting of a cage having a base provided with a central opening to receive said plate on said handle, and having internal recesses for the passage of said projecting clamping members, said guard member and said supporting member being adapted to be relatively revolved to throw said clamping members out of alinement with said recesses to secure said cage.

4. A lamp-guard comprising in combination, a supporting member consisting of a handle provided with a central opening, a

threaded sleeve mounted in said central opening and projecting beyond one end of said handle, said handle being provided with an annular recess at said end, a plate having a central opening mounted on said end of said handle and fitting said recess adjacent said central opening, projecting supporting-arms on said plate, projecting yielding clamping devices on said plate,- a washer of non-conducting material on said sleeve, a nut disposed on said sleeve and bearing on said washer, and a guard member consisting of a cage having a base provided with a central opening'to receive said plate on said handle, and having internal recesses for the passage of said projecting clamping members, and projections on said base adjacent said recesses over which said clamping members are adapted to be sprung when said guard member and supporting member are relatively revolved.

In testimony whereof I have signed my name in presence of two subscribing witnesses.
